The family of Leezandra Aponte, 36, of Lowell, identified the mother of three as one of the victims on Wednesday afternoon. Aponte died at Lahey Hospital.

Eight people were taken to area hospitals, treated and released. One person, a 55-year-old man, remains hospitalized with serious injuries, according to the district attorney's office.

An auction employee in his 70s was behind the wheel of the 2006 Jeep Grand Cherokee when it apparently lurched out of control and mowed people down.

Witnesses praised the response from workers and first responders.

"You heard like this explosion or a bang, and all of a sudden, you could hear a pin drop," said Randy Miller of Onyx Preowned Vehicles.

Miller said he has been going to the auto auction for about 10 years. He said that at first, no one was sure what had happened, but that quickly changed.

"I feel like they did a really good job responding in such a panic situation," he said. "They got all the people pushed back. They got a good circle open. Fire trucks were getting ready to come in."

Among the first responders was Billerica fire Capt. Bill Paskiewicz, who was working a detail at the auction.

"I came around the corner and saw numerous people that were severely injured," he said.

Paskiewicz said he had to deal with several things at once.

"Minor hazmat from fluids leaking. We had building integrity from the impact from the car. We had the car, still in gear and running," he said.

"It was kind of chaos, but people there at the auction, they really started organizing everything immediately," said Eduard Fandunyan of Sevan Auto Group.

Fandunyan said he had been standing near the Jeep minutes before it accelerated. He said he also had nothing but praise for the response by the auction house and emergency responders.

"They pushed the people out so it was easy access," he said.

On Thursday, the auto auction company said it will increase safety precautions at the facility.

"We will be installing barriers, or 'bollards,' to help keep vehicles from veering out of their intended lane. Sturdy, vertical posts, bollards are frequently used on highways to control road traffic and will provide additional protection for our patrons and everyone working at the auction," Lynnway Auto Auction President Jim Lamb said in a statement.

The cause of the crash is still under investigation, but officials said it appears to have been accidental.
